Ok, fairly straight forward issue.
I have a home built cube built on a Ramps 1.4 setup marlin 1.1.5 . The fan control works great, on at 2nd layer off when its done all good.
Then I tried to pause the print and I noticed the fan was not on after I resumed....
I don't know what M code is in use to pause and then resume so I cant test if its a marlin issue or an AstroPrint issue. I am of course pausing from the AstroPrint web interface. So starting here to see if I can get some direction to test this direct from a GCODE pause/resume effort and rule out AstroPrint. Latest version of all things involved BTW..
